The FastLabel Label Sleeves are an innovative way to adhere labels to bottles. They work by heating the Fastlabel with a custom label of your choice on the bottle. The Fastlabel will contract, sticking the label to the bottle. They are easy to remove as well, simply cutting and peeling. No more gummed up bottles! These Fastlabel Label Sleeves are specifically for 12 oz beer bottles, but other sizes are available as well.
